FIELD OF THE INVENTION

The present invention relates generally to an apparatus for a playground. More specifically, this invention is an apparatus that consists of different types of playrooms and trampolines that allows a user to perform various types of task.

BACKGROUND OF THE INVENTION

A playground is a perfect place to let children run free, get fresh air, and exercise. Typically, playgrounds only consist of a few features such as monkey bars, jungle gyms, and basketball courts. Thus the children are provided with only a limited amount of things to do. This can be problematic because children can often bore of something very quickly which can then cause problems for the parents. Additionally, traditional playgrounds do not provide entertainment for the parents. It is therefore an object of the present invention to provide a playground with a plurality of playrooms and features that can entertain the children endlessly.
